I remember when one of my clients came to me upset. She'd had more refund requests than ever and took that personally, making it mean that she was doing a terrible job and wasn't offering enough value. Her confidence tanked and so did her sales afterwards as a result, but the reality was that more customer service issues came with having more customers. It's a normal part of business and it's actually a sign of growth. Listen. There is no way you can make everyone happy. It's impossible. There will be issues.
They're inevitable. And while you should be made aware of any patterns that are noticed, you need to implement 3 rules to protect your energy. One, all customer service issues should be directed to one email, not allowed in the client community if there is 1, not spread out over various platforms. They should all have one hub and ideally going to 1 email. Two, someone else should've filled all of those customer service emails. The email should not be your email. In fact, you should not even see them unless there's an issue that must be escalated, and there is no one else to handle it. Your business cannot afford to have you, your client facing team or even your growth team bombarded with customer issues that will cause the team to doubt the transformation that you offer, to drop their confidence level or their enthusiasm.
Three, set policies, draft templates to common issues, like failed payments, refund or cancellation requests, etcetera, and automate wherever possible, and then consistently enforce. Take the guesswork out of it. No special circumstances, no case-by-case decisions. The rules apply to everyone. It's not personal, it's policy. These 3 steps will protect your energy when customer service issues inevitably increase. My advice is to implement them now even if you don't think it's necessary. You will one day need them, and this will ensure you're ready whenever that time comes.
